Fear of the Colonized Other in Richard Marsh's The Beetle
<p>This thesis argues Richard Marsh’s Victorian novel The Beetle offers a critique of British colonial practices through the reverse colonization experiences had by British characters in the novel. Intrusive, exploitative actions perpetrated by the British subjects in the novel invite reciprocal …

Phenotypic and Molecular Characterization of the Beetle Pathogens Paenibacillus popilliae and Paenibacillus lentimorbus
DNA similarity studies were used to determine the species of thirty-one strains of bacteria isolated from the hemolymph of infected larvae from Mexico and throughout Central and South America. Twenty-one of the strains were determined to be <I>Paenibacillus popilliae</I> and ten were found to be …

Patterns of Hemolymph Pressure Related to Tracheal Tube Collapse in the Beetle Pterostichus commutabulis
… gas exchange in multiple orders of insects. The underlying mechanism driving this phenomenon is not known. Among other things, tracheal tube collapse could be caused by either direct impingement of trachea or by a difference of pressure gradients between the intra-tracheal air and the …

Speciation and diversification of the beetle tribe Cratopini on the islands of the South West Indian Ocean area.
The aim of this thesis is to examine a spectacular radiation of phytophagous beetles (Curculionidae: Entiminae: Cratopini) that inhabit the islands of the South-Western Indian Ocean. As there are no previous molecular studies of these beetles, it was necessary to take a varied approach that …

Investigating the roles of candidate gap genes from the neuroblast timer series during axial patterning in the beetle Tribolium
The gap genes encode transcription factors that play a central role in the process of segment patterning in Drosophila. Specifically, they interact to form the well-characterised ‘gap gene network’, which directs the formation of segment boundaries (through regulation of pair-rule genes), and the …

Development, Optimisation and Characterisation of a Radiation Hard Mixed-Signal Readout Chip for LHCb
The Beetle chip is a radiation hard, 128 channel pipelined readout chip for silicon strip detectors. The front-end consists of a charge-sensitive preamplifier followed by a CR-RC pulse shaper. The analogue pipeline memory is implemented as a switched capacitor array with a maximum latency of 4us. …

Initial assessment of the polyphagous shot hole borer (PSHB) in indigenous Afrotemperate forests
The polyphagous shot hole borer or PSHB (Euwallacea fornicatus) is an invasive ambrosia beetle native to Southeast Asia. In 2017 it was discovered in Pietermaritzburg, South Africa, where it was found attacking several ornamental tree species, and has since spread into eight of the nine provinces …

Development and Characterisation of a Radiation Hard Readout Chip for the LHCb-Experiment
Within this doctoral thesis parts of the radiation hard readout chip Beetle have been developed and characterised, before and after irradiation. The design work included the analogue memory with the corresponding readout amplifier as well as components of the digital control circuitry. An interface …

A contribution to the study of the habits and bionomics of the Stenoscelis hylastoides (Woll.), a wood-boring beetle pest of the Western Cape Province
The beetle Stenoscelis hylastoides (Woll.), first described in 1861 is a wood borer of quite considerable economic importance in the Western Cape Province of South Africa. Because it was not until recently that its effect on house timbers was noticed, it has never before been thoroughly …

Coexistence and resource use in space and time in a West African tortoise beetle community
… forests and coral reefs are usually regarded as the epitome of complexity and diversity. The mechanisms, however, that allow so many species to coexist continuously, still need to be unraveled. Earlier equilibrium models explain community organization with a strict niche separation and …

Beetle exoskeletal structure and surfaces determine specialized functions: Two case studies
The exoskeletal cuticles of insects are made of materials that could have a wide range of material properties, leading to numerous structures and surfaces with selective advantages. Some of them are functional specifically for interacting with other biological structures or the environment. This …

Megacerus discoidus, a potential biological control agent of hedge bindweed in southwestern Virginia
… one generation a year. Overwintering occurred in the 4th instar. Larvae fed on 40-50% of the seed content before diapause and the rest of the seed in the following spring. When more than one larvae attacked a seed, only one adult emerged because of cannibalism, which was most common among 2nd and …

Assessment of the Potential Role of Blizzard Damage in the Spatial Distribution of Southern Pine Beetle Infestation in Unicoi County, Tennessee.
<p>The Southern Pine Beetle, or SPB, (<em>Dendroctonus frontalis</em> Zimmerman) is a bark beetle that is endemic to the Southern forest ecosystem. Beetle populations remain stable for years at a time; however, for reasons not fully understood the beetle undergoes accelerated population growth on …

Phylogenetic relationships among beetles within the genus Onymacris (Coleoptera : Tenebrionidae) : a phenetic versus cladistic approach
Phylogenetic relationships among species within the beetle genus Onymacris (Coleoptera Tenebrionidae) are identified using phenetic and cladistic approaches. Phylogenetic results from cladistic analyses proved to be more robust than those derived with phenetic approaches. However, phenetic analyses …

Host plant relationships and chemical communication in the cerambycidae
The beetle family Cerambycidae is one of the largest groups of insects. Commonly referred to as longhorned beetles, the larvae of cerambycids usually feed on the tissues of woody plants and can be important insect pests, damaging and even killing trees in managed and natural landscapes. In this …

Impact of elevated carbon dioxide and increased temperature on Japanese beetle herbivory
To examine how the major elements of global change affect herbivory in agroecosystems, a multi-factorial experiment was conducted in which soybeans were grown at two levels of carbon dioxide and temperature, including those predicted for 2050, under otherwise normal field conditions. Japanese …

Japanese beetle Popillia japonica Newman: foliar feeding on wine grapes in Virginia
The natural infestation level for 1985 of the Japanese beetle, Popillia japonica Newman, in the Shenandoah Valley of Virginia failed to reduce berry quality, yield or shoot growth in a commercial vineyard. Intensive postveraison foliage feeding by Japanese beetle resulted 1n fruit with lower …

Bioinspired scattering materials: light transport in anisotropic, disordered systems
The study of light propagation in disordered media has attracted the interest of many researchers for its relevance to fundamental and applied problems, ranging from imaging through turbid media to the fabrication of white paint. Scattering in a disordered system is determined by the spatial …
